xDSL Port Setup

This chapter explains how to configure settings for profiles and individual ADSL ports. It also covers how to configure virtual channels and virtual channel profiles.

13.1 ADSL Standards Overview

These are the ADSL standards and rates that the IES-612-51A supports at the time of writing. The actual transfer rates will vary depending on what the subscriber’s device supports, the line conditions and the connection distance.

13.2 Downstream and Upstream

Downstream refers to traffic going out from the IES-612-51A to the subscriber’s ADSL modem or router. Upstream refers to traffic coming into the IES-612-51A from the subscriber’s ADSL modem or router.

13.3 Profiles

A profile is a table that contains a list of pre-configured ADSL settings. Each ADSL port has one (and only one) profile assigned to it at any given time. You can configure multiple profiles, including profiles for troubleshooting. Profiles allow you to configure ADSL ports efficiently. You can configure all of the ADSL ports with the same profile, thus removing the need to configure the ADSL ports one-by-one. You can also change an individual ADSL port by assigning it a different profile.
